Hi, I'm working on a system of 2 differential equations. My initial condition (t=0) is c(100,0) and i'm using lsoda function (from package deSolve) to solve it. My system reprensents the evoution of drug concentration in two compartments throug time. Problem is I would like to model a repeated drug administration. That is to say, not only 100 at t=0 but also at t=20,40,... I can't find a solution to do so. I tried adding "100" to the first differential equation at the times of interest but it doesn't work. Do you have any idea?
Thank you F.G.
